I actually did that. I have a zoa garden (well garden in the making lol) and moved that rock to the back of the tank where the RG hangs and the other two stay more toward the front of the reef.The damsel for sure.
Wouldn't hurt to move a few rocks around either. You want to "scold" the aggressor, not "punish" the the one being bullied. Moving some rocks around might reestablish the damsels space too. Your other fish will be able to lay claim to some real estate before the bully gets put back in.
I did NOT know that!Damsels are damsels, they all get quite aggressive eventually IME.
You do realize your clowns are in the damsel family also? Kind of explains why they are so mean at times too.
Thank you for clarifying who gets a time out.
